Why wait on a "round" to send stuff out?
Keep a record (date sent, what kind of a response if any) who you've sent to, and as you find a new name to query, send off your stuff. Make it a constant thing. A query a week means you've got 52 of them in circulation.
Two months is not long at all. Yeah, the website or guidelines may say two weeks or so, but that's got little to do with reality.
Make sure you constantly have queries circulating. That way if you get a rejection you say, "So what? I've got 51 others out there."
And while you wait WORK ON THE NEXT BOOK.
If an agent falls in love with your stuff she'll want to know what else you have finished.
If you get a comment in the margins, take it as manna from on high, and use it.
It took two years, several complete rewrites, and I was well into my third book before I got the phone call. By publishing standards that was lightning fast! During that two years I was working, not waiting.
The comment that turned things was an agent telling me (in a nice way) "I just couldn't sympathize with the character."
I took it to heart, added ONE LINE, and the next time out it sold. They bought the other novels at the same time.
Good luck!
